' PENFIELD AND ELMORE PENFIELD, OF SAME PLAGE.

IMPROVED TAcKLi-z-HOOK- Specification forming part of Letters Patent No. 48,336, dated June 20, 1865.

To all whom it may concern.'

Be it known that I, RUSSEL FRISBIE, of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and Improved Tackle-Hook; and l do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawings, forining part of this specitication, in which- Figure l represents a section-.ll side elevation of this invention, the line .1: fr, Fig. 2, indicating the plane of section. Fig. 2 is a horizontal section 'of the Same, taken in the plane indicated by the line y y, Fig. 1, and showing the strap open in red and closed in black outlines.

Similar letters of referenceV indicate like parts.

This invention consists in a strap which swivels on the shank Ot' a tackle-hook, and which is made in two parts connected by a pivot, in combination with aspring-bolt which locks into a notch i on the tip ot' the heck in such a manner that when the strap is locked to the tip the hook is et't'ectually closed and prevented from unhooking spontaneously, and by pressing back the bolt the strap can be readily unhooked and turned up, so as to Open the hookv at any moment. Furthermore, by the use Of this strap the hook is prevented from straightening out, and it is capable to sustain a much greater strain than it could without the strap.

A represents a hook, cast of metal or made of any Suitable material in any desirable manner. The shank of this hook is provided with a neck, a, calculated to receive the strap B.

This strap is made ot' two distinct parts, c r1, which are united by a pivot, b, so that the part d can be turned up or down to any desired angie, and the Whole strap swivels on thc shank oi' the hook in either direction. The part dof the strap is provided with a loop which catches over the tip of the hook, and in order to lock the same a springbolt, e, is placed in the interior, which is made to catch into a notcl1,f, in the tip of the hook. This bolt is secured to a sleeve, g, which ts loosely7 over the strap, and which may be provided with buttons, so that it can be readily i'orced back. By pressing back this sleeve the bolt is withdrawn from the notch in the tip and the strap can be turned up and out to the position shown in red Outlines inFig. 2. When this is done the hook is open, and it can be freely hooked to a rope or other article, or unhooked therefrom. When the hook is adjusted the strap is locked by pressing it down over the tip, and it eft'ectually prevents said hook from unhooking spontaneously. Furthermore, by the 'use ot the strap the hook is strengthened and enabled to sustain avery great strain without straightening.

I am aware that straps have been applied to tackle-hooks, and I do not wish to claim the use of the strap as my invention; but

I claim as new and desire to secure by Letters Patent- A strap which swivels on the shank of a tackle-hook and is made in two parts that are hinged together, in combination with a spring bolt, constructed and operating substantially as and for the purpose set forth.

RUSSEL FRISBIE.
